Application filed September 16, 1925. SerialNo 56,717. 1

Retaining valves are applied to cars to make the'movement of a train ofcars safe, and to, conserve the supply ofv air, and this valve when setand inv good working order, does not allow all of the air to escape fromthe brake cylinder, but retains a certain amount of pressure thereinsuflicient to hold the brakes in a set position, while the. air. isbeing replenished in the train line. lV hen the air pressure in thelineisfincreased' or replenished if the retaining valve is 'inaninoperative condition, the triple valve will automatically assume areleased position allowing the train to gain momentum, and

run out of control. It is, therefore of the utmost importance that theretaining valve be in good'working order at all times.

The practice in vogue :prior to my inven tion was to bolt'the retainingvalve through the car end wall, but this practice has been foundobjectionable in that the bolt holes i in the car wall graduallyincrease in diamebe loaded, the load must be removed The object of myinvention is to provide an anchor for a retaining valve so mounted onthe car and of such construction that theretaining valve may be detachedfrom and applied to the anchor without removing the load from the car,thereby reducing the expense of repairs to a minimum, and elimi natingthe possibility of damage and. loss of the contents of the car.

The referencenumeral' '13 designates aretaining valve of standardconstruction-provided with side'ears 14 and an operating handlelf),theears 14 being provided with suitable bolt openings. Y 1. I v As shownin the drawings, my. anchor or bracket is susceptible of manymodifications or embodiments without departing from the spirit of myinvention.

In the embodiment shown'in Figures 1 to a the anchor comprises a mainbody plate 16 having bolt or rivet openings 17 near its upper edgethrough which bolts or rivets pass to secure the anchoror bracket to thecar-in a suitable position, at the lower end of the body plate I providea rebent portion which COIISlSlJS' of. a. forwardly extending spacingmember 18 from the forward edge of which a flange 19 extends; upwardlyand I substantially parallelwith the, body plate 16. This flange'l9,is'providedy, with elongated s-lots 20, spaced to coincide with. thebolt openings in; the ears] 1% oflthewaive,

said slots being open atthe upperedge of the flange 19 as shown. y V 7If desired, lugs 21 maybe formed on the elongated slots 20 to functionas rests supports for the head of the bolts supportlng the-boltsin anadJuSted position before the nuts 24 are tightened, Again,

these lugs also function too as abutments to prevent the bolt turningwhile the nut is being screwed on and oti'the bolt as' will beunderstood. j H I a H In Figures 5 and 6 tl'1econst-ruction issubstantially the same as shown in Figures-i to 4 the difierence beingthat the flange 25.,

extends to the top "edge of the body plate 26. as. clearly showninFigure 6, and the body plate 1s provided with cars 27 extend ing fromits ends, which ears are provided with bolt openings 28 through whichbolts pass to secure the anchor. to the cars. The flange '25is provided;with elongated 29 corresponding with the slots 20 of ure 3. ii

In Figures 7 to 9 the construction of the bracket or a'nchor is likethat-shown in Figslots ures 1 to 1, the difii'erence residing inproviding the edges or, side walls of the elongated slots with proect1ons 30-and depressions 31, the progections 30 on one side of theslot being oppositethe depression 31 on the other side of theisame slotthereby torming a substantially sinuous slot in the flange 32 of thebody plate 33v whereby the bolt will be held inthe depressions 31 inpre-v "l'iininarrf ad'usted osit-ion;

I-nFigures 10 to 12 the construction is practically the same as shown inFigures 7 toll, the only dilterence being that the projections 3a andthe depressions 35 are formed-on curves as "distinguished from theangular -i'ormation shown in Figure 7. In

7 Fi ures 10 to 12, 36 designates the body pla teland 37 the flange.

In. use my improvedbracket or anchor is bolted or riveted to the wall ofthe car 'permanently in the desired positions, the

rivets passing through the openings in the body plate.

7 Now in mounting the valve on my anchor the bolts 22 may be looselymounted in the holes injthe ears 14 of the valve or they may be looselyplaced in the elongated slots with.

a the heads of the bolts between the body plate and the flange. In thefirst application the bolts 22 are positioned near the top oi. theelongated slots so that if for any reason it is necessary to shorten theair pipe 37 the bolts may be placed ina lower posit-ion inthe slotsas'will be understood.

When the valve and bolts 22 are in proper position relative to theanchor the nuts 24 are tightenedfthereby securing the valve to V theanchor firmly.

It will be seen th'atthe valve may be ap plied to and detached from thecar with out entering the car.

What I claim is:

1. A bracket for a retaining valve comprising a fiat plate having areturn Lip-- owardly extending spaced flange at its'lower end providedwith elongated slots open. at

the upper edge of the flange, said plate having bolt openingsthrough-it.

2. A bracket for V retaining valves comprising a flat plate having boltopenings,a

spacing member extending forwardly from the lower edge portion oftheplate, a flange extending upwardly from said spacing 1nen1- her andsubstantially parallel withthe said plate, elongated slots in saidflan e-open at'th'e top edge of the flange ant. means on the flange to supporta bolt in vertically adjusted position in said slots.

3. A bracket for retaining valves cont.

prising a flat plate having bolt openings, spacing member extendingforwardlytrom the lower edge portion of the plate, a flange extendingupwardly from said vioron nanis'nnr;

spacing spacing 1 member and substantially parallel with the
